WILLIAM RICHARDSON, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO COCKLE SEPARATOR MANUFACTURING COMPANY, OF SAME PLACE.

COGKLE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 239,195, dated March 22, 1881. Application filed December 17, 1880. (No model.)

rating cockle, broken berries, and other impurities from Wheat, and is designed as an improvement on the well-known Kurth machine, whereby the cockle and broken berries are 4 separated from each other after they are can ried out of the wheat.

Figure l of the drawings is a perspective view of a cylinder and frame of a machine embodying myinvention, with part of the cylinder and frame broken away. Fig.2 is an end view of the same, and Fig. 3 is a detail.

A is the cylinder, indented, made slightly tapering, and adapted to being revolved as usual.

B C are catch-boards, of wood or any other suitable material, and having grooves in one edge to receive strips of rubber or other flexible material, 0, which strips are adjustable out and in and are secured in place by bolts 0. These catch-boards have trunnions I), attached o eccentrically at each end, which are designed towork in. bearin gs in brackets E, attached to standards F by bolts passing through slots 6,

so as to be adjustable in and out. After the trunnions have been passed through into their 3 5 bearings, I provide them with collars d, held in place by set-screws D,and these set-screws also regulate the inclination of the catchboards, as they (the set-screws) rest upon pins E, which project out from the brackets E.

I arrange the catch-board C in the position usually occupied by the single catch-board in machines of this character, and so that it will guide the cockle into the trough H and I fix the second catch-board, B, a short distance above it. Now, after loosening the set-screws,

I adjust the collars d on the trunnions D so that the rubber strips 0 will rest lightly against the inner face of the cylinder, most of the weight of the overbalanced edge of the board being sustained by pins E and set-screws D. Above catch-board B, I attach the brush L.

Operation As the wheat falls into the cylinder the cockle and broken berries are deposited in the indentations, and are carried up be- Y yond the first catch-board, C,when the cockle, 5 being heavy-and round, will topple out onto it, and will be conveyed into trough H but the broken berries, being light and of irregular sh apes, become wedged in the indentations, and, clinging as they do, are often carried very 6o much higher. I therefore provide the second catch-board, B, which, receiving the broken grain as it is dislodged from the indentations by the brush L, will guide it into the trough H, to be discharged into a separate receptacle from that which catches the cockle, and it may thus be saved without further trouble.

What I claim is-- 1. In a grain-separator, the combination, with the cylinder having indentations or pock- 7o cts upon its interior, of two catch-boards arranged one above the othcr to receive successively and separately deliver matters which, by reason of their difl'erencein form and weight, fall from said indentations or pockets at different inclinations thereof, as set forth.

2. In a grain -separator, the combination, with the cylinder having indentations or pockets upon its interior, of two catch-boards, independently adjustable, and arranged to receive successively and deliver separately those matters which, ,by reason of their difference in form and weight, fall from said indentations or pockets at different inclinations thereof.

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of December, 1880.

WM. RICHARDSON.
